on the 6th. These nesting places had been visited by other 
parties between my visits. 
Sterna hirundo (70). Common Tern. 
“In North America chiefly confined to the Eastern Provin- 
ces, breeding variously throughout its range” (A. O. U.). Ap- 
parently migratory, three specimens were taken on May 6 (’76, 
Resler) out of a number seen at Patapsco marsh ; and on May 
17 (93), one was shot at the same place. On September 
1 (98, A. Wolle), four were shot out of about fifteen at Gun- 
powder marsh, these I examined. 
Sometimes common, but an irregular migrant at Washington 
(Richmond). 
Sterna paradisza (71). Arctic Tern. 
Breeding from Massachusettes northward, this species comes 
south in winter along the Atlantic coast at least as far as Vir- 
ginia. 
Sterna dougalli (72). Roseate Tern. 
This southern species, going regularly north in summer to 
Maine, “ doubtless breeds” at Cobb’s Island (H. B. Bailey, 
Auk, i, 24-28), and is a “rare straggler on the New Jersey coast 
during summer ; formerly it is reported to have bred in consid- 
erable numbers” (Birds E. P. and N. J., 47). 
Sterna antillarum (74). Least Tern. 
A summer resident in restricted localities, this species is usu- 
ally seen during migrations. 
On June 13, (’94), I visited a nesting colony at the juncture 
of Miles River with Eastern Bay, where, on a small island, I 
found four sets of three; twelve of two, and eight single eggs ; 
how many other nesting hollows it is impossible to say, as 
they are so slight they show no signs of a nest until an egg is 
deposited. During the fall of 1893, this species was noted at 
Lake Roland on August 19 and 20, and September 3 and 
4 (Fisher).
